How to know if you have insomnia: an honest self-check against the NHS definition

If you are in crisis or feel unsafe, please call 999 or go to A&E. For urgent mental health support, call NHS 111 and select the mental health option. Samaritans (116 123, free, 24/7) and Shout (text 85258) are always available.

You know you have insomnia if you regularly have problems sleeping, which the NHS describes as finding it hard to go to sleep, waking several times in the night, lying awake, waking early and not getting back off, still feeling tired after waking, or being tired, irritable and unable to concentrate during the day because of it. The word doing the work in that sentence is regularly. One dreadful night before a job interview is not insomnia, and neither is a rough week around a house move. A pattern that keeps repeating, and that follows you into the next day, is.

That is what this page walks through: the NHS definition in plain terms, a self-check you can honestly measure yourself against, the difference between a bad patch and the real thing, and the point at which it stops being a self-help job. It is not a diagnostic tool, and if you recognise yourself in a lot of it, your GP is the right next step. If sleep has become something you actively dread, the hub guide on sleep anxiety symptoms covers that side in detail, and this page sits alongside it.

If your mind will not switch off, tell a therapist what it is circling. You get a personal video back, usually within hours.

Is there a test that tells you if you have insomnia?

No. There is no online quiz that can hand you a diagnosis, because insomnia is defined by a pattern over time rather than by a score on a given day. Any questionnaire will reflect how you happened to answer that afternoon, after that particular night, and a high score is not a verdict any more than a low one is a clean bill of health.

What a self-check can honestly do is help you notice the pattern. The NHS definition of insomnia is short and specific, which makes it a better yardstick than a ten-question quiz with a traffic-light result. The list further down this page is built from that definition and deliberately has no score attached.

What insomnia actually means

The NHS describes insomnia simply as regularly having problems sleeping, and adds one line that most people searching for this page do not expect: it usually gets better by changing your sleeping habits. Mind describes the same thing, noting that finding it hard to fall asleep, stay asleep or waking earlier than you would like is known as insomnia when it happens regularly.

The NHS also draws a line based on how long it has been going on. Insomnia that has lasted less than three months is called short-term insomnia, and insomnia that has lasted three months or longer is called long-term insomnia. You do not need to reach the long-term mark before you act on it, but the distinction is a useful check on catastrophising: a fortnight of bad nights is a real problem, and it is also not yet the entrenched thing your 3am brain may be insisting it is.

One more piece of the definition is worth having. The NHS notes that everyone needs a different amount of sleep, with adults needing 7 to 9 hours on average, and that you probably are not getting enough if you are constantly tired during the day. The daytime is part of the evidence, not just the night.

The self-check: what the NHS says insomnia looks like

This is a reflection list, not a test. It is drawn directly from how the NHS describes the symptoms of insomnia, and the honest question to ask against each line is not "has this ever happened" but "does this happen regularly".

At night

• You find it hard to go to sleep
• You wake up several times during the night
• You lie awake at night
• You wake up early and cannot get back to sleep
• You still feel tired after waking up

During the day

• You feel tired and irritable
• You find it hard to concentrate because you are tired
• You find it hard to nap even though you are exhausted

If several of those are regular fixtures rather than occasional visitors, and they have been for weeks, the NHS definition fits well enough to take seriously. If most of them are strangers and you are here because of one bad stretch, that is worth knowing too, because worry about sleep can quietly become part of what keeps poor sleep going, and the guide on anxiety and insomnia covers how that loop works and what to do about it.

What is the difference between a bad patch and insomnia?

A bad patch is poor sleep with an obvious cause and an end in sight, while insomnia is poor sleep that has become a regular pattern, often outlasting whatever started it. The NHS lists the most common causes of insomnia as stress, anxiety or depression, noise, a room that is too hot or cold, an uncomfortable bed, alcohol, caffeine or nicotine, jet lag and shift work. Plenty of those are temporary. A deadline, a heatwave, a fortnight of late-night coffee: the sleep problem arrives with them and often leaves with them.

The thing to watch for is when the cause goes and the sleep problem stays. Mind describes a cycle where poor-quality sleep leads to tiredness, tiredness makes daily life harder to cope with, that difficulty feeds worry and stress, and the worry and stress lead back to poor sleep. Once that loop is turning, the original trigger stops mattering very much, and a bad patch has quietly become the thing the NHS calls insomnia.

The NHS also lists a range of other conditions and medicines that can cause or contribute to insomnia, from restless legs syndrome and an overactive thyroid to the menopause, and separately flags snoring or interrupted breathing during sleep. None of that is for you to work out from a webpage. It is the reason a GP is the right person to see once a pattern has set in, because part of their job is to find out what is actually causing it.

Is it insomnia or is it anxiety?

Often it is both, because the NHS lists stress, anxiety and depression among the most common causes of insomnia, and lists not being able to sleep among the mental symptoms of anxiety. The NHS is direct on what to do with that: do not self-diagnose, and speak to a GP if you are worried about how you are feeling. What you can do without a diagnosis is notice the shape of it, and if the nights are bad mainly because your mind will not stop, the practical guide on how to sleep with anxiety covers what to do at 2am and, more importantly, during the day.

What to do if the list felt familiar

Start with the habits, because that is where the NHS starts. Its self-help advice is to only go to bed when you are sleepy, to get up at the same time every day, to wind down for at least an hour before bed, to keep the bedroom dark and quiet, and to exercise regularly during the day. It advises against alcohol, tea, coffee or smoking in the six hours before bed, big meals late at night, screens right before sleep, daytime naps, and sleeping in after a bad night rather than sticking to your usual hours. None of it is glamorous, and the NHS position is that insomnia usually gets better this way.

Alongside the habits, deal with what is driving the worry. The NHS suggests talking about your feelings to someone you trust, regular exercise and calming breathing exercises, and not reaching for alcohol, cigarettes, gambling or drugs to take the edge off. If what you want is a qualified person to look at your specific situation rather than a general list, that is the gap Wobble was built for. You describe what is going on, and a qualified UK therapist sends back a personal video with one or two practical things to try, shaped by the Wobble response framework, a structured framework built for short, practical, single-response support. Wobble's Clinical Lead is James Penney, an NCPS Accredited Psychotherapeutic Counsellor.

When to see your GP

The NHS is specific about the threshold. See a GP if changing your sleeping habits has not helped, if you have had trouble sleeping for months, or if your insomnia is affecting your daily life in a way that makes it hard for you to cope. You do not need to arrive with the word insomnia proven. The list above is a reasonable script for that conversation.

A GP will try to find out what is causing it so that you get the right treatment. The NHS says you may sometimes be offered cognitive behavioural therapy, either face-to-face with a therapist or through an online self-help programme, and that you may be referred to a sleep clinic if there are signs of another sleep disorder such as sleep apnoea. The NHS also notes that GPs now rarely prescribe sleeping pills for insomnia, and any questions about medication belong in that GP conversation rather than on a webpage.

In England, if you are 18 or over (16 or over in some areas), you can also refer yourself directly to an NHS talking therapies service without going through your GP, though waits vary widely. In Scotland, Wales and Northern Ireland, your GP can point you to the local route. A BACP, UKCP, BABCP, BPS or NCS-registered therapist can help privately, and BACP (bacp.co.uk) and Counselling Directory (counselling-directory.org.uk) let you filter for experience with sleep and anxiety.

Seek urgent help if you are having thoughts of suicide or self-harm or feel you cannot keep yourself safe. NHS 111 has a 24/7 mental health option, Samaritans (116 123) are free to call day or night, and Shout (text 85258) is there if calling feels like too much.

Quick summary

You know you have insomnia if you regularly have problems sleeping: trouble getting off, waking several times, lying awake, waking early, still feeling tired on waking, or being tired, irritable and unable to concentrate in the day because of it. No quiz can diagnose it, because it is a pattern over time rather than a score. The NHS lists stress, anxiety and depression among its most common causes and says it usually gets better by changing your sleeping habits. If that has not helped, it has gone on for months, or it is making daily life hard to cope with, see your GP, who may offer cognitive behavioural therapy. In England you can also self-refer to NHS talking therapies. You do not have to sort this alone.
